  Security Headers

  Only 1 out of 6 modern security headers found. Missing: x-frame-options, x-content-type-options, content-security-policy, referrer-policy, permissions-policy. The site is exposed to XSS (no CSP), clickjacking (no X-Frame-Options / CSP frame-ancestors), MIME-sniffing (no X-Content-Type-Options), and HTTPS-stripping MITM (no HSTS). Mozilla Observatory grades sites with <4 headers as D or F.

  HTTP Requests Count

  The page loads 249 external resources — this is too many (2 CSS, 27 JS, 185 images). A high number of HTTP requests critically slows down page loading, as browsers are limited to 6 simultaneous connections per domain. This negatively affects all performance metrics.

  Knowledge Panel Readiness

  Low knowledge-panel readiness — score 25/100. AI search engines and Google Knowledge Panel cannot confidently identify this brand. The cheapest, fastest fixes are: (1) add Organization JSON-LD with a sameAs chain (Wikipedia, Wikidata, LinkedIn, Crunchbase, GitHub, social), (2) make NAP (Name/Address/Phone) visible in the footer or contact page, (3) create a Wikidata entry (low notability bar), then (4) pursue Wikipedia once notability is established.
